There are numerous soundtracks which people use in training for how fast to do the compressions in CPR – the following is my favourite – if you watch ANY UK TV or BBC News (UK or International) you will know the tune! I use this in training classes as an introduction to the session and people get the speed of compressions from the music very quickly!
The second timer is the beat – 2 compressions each second! EASY!
